摘　　要：以盘县孔官小流域为例,从土地资源利用现状特点和存在问题入手,在地理信息系统软件ARCG IS和ARCVIEW支持下,选择小流域土地利用、土地石漠化、坡度、土壤、植被、气候等生态因素,按照土地资源自然地带规律、土地适宜性、土地生态系统保护、农业经济多样化相结合,探讨经济效益和生态效益统一的农业土地利用模式,并提出模式实现的保障措施。Taking Kongguan river basin in Panxian county as an example, the paper puts forward the concept of designing models for agricultural land use in rock desertification mountainous area and methods. This paper analyzes features and problems of land use and divides Kongguan river basin into five areas by means of ARCGIS and ARCVIEW software based on important ecological factors： land use, rock desertification, elevation, soil, vegetation, climate. Agricultural land use models should observe the principles which include physical geographical factors, land suitability, agricultural ecosystem protection and divers agricultural economy.
